The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
scdbackup is a simplified CD/DVD backup program for Linux. It can back up large amounts of data on one or more media, with no special tools needed for reading the backup. It supports ISO9660 filesystems and afio archives. Its special features are automatic division of data into multiple volumes, verification of write success, incremental backups, a search and restore helper for large ISO9660 backups. CDs get written via cdrecord, wodim, cdrskin, or xorriso. DVDs and BDs get written via growisofs, cdrskin, or xorriso.
g4u ("ghost for unix") is a boot-floppy/CD that allows one to easily clone PC hard disks by using FTP. This is often done to deploy a common setup on a number of PCs. The floppy/CD offers two functions: it uploads the compressed image of a local hard disk to an FTP server, and then it can retrieve that image via FTP, uncompress it, and write it back to disk. Network configuration is fetched via DHCP. As the hard disk is processed as an image, any filesystem and operating system can be deployed using g4u. Easy cloning of local disks as well as partitions is also supported.
LazySync is a file-synchronization program written for handheld devices using the SavaJeXE Java operating system. It attempts to offer similar functionality to HotSync and ActiveSync of the Palm and CE platforms, and supports synchronization via an existing TCP/IP network connection between handheld and host.
